babble
This term evokes a sense of rapid, unstructured sound, whether human or natural. When applied to speech, it carries a connotation of immaturity or lack of control, ranging from the innocent vocalizations of an infant to the frantic, nonsensical chatter of an adult in a state of excitement or confusion. In a natural context, the word describes the rhythmic, melodic quality of water. This creates a sensory contrast where the same word can describe both irritating noise and soothing environmental sounds. As a noun, it is typically uncountable when referring to the general quality of incoherent speech.
